This driver is design to allow communication with E+E Elektronik's EE210 humidity sensor, via the ezeio MkII's Modbus serial port. The driver may be compatible with other E+E humidity sensors with Modbus connectivity, such as EE072, EE150, and EE211.

Name - The name is up to the user. Our suggestion is to choose a naming convention that makes the viewing the device list intuitive. Such as referring to the sensor and/or application. Keep the name short as it will be combined with the register name to create the default “Field” name (if added to “Fields”)

Active Check box - Check this box and “Save changes” to run the driver. The driver program can be suspended by unchecking the box and clicking on “Save changes”.

User Notes - This space can be used to store information specific to the device and your application, such as: location, wiring, scaling, etc.

eze System Notes - In this space we provide: wiring instructions, product image, product details.

Modbus Address - Enter the devices unique Modbus address (device ID)

Device model Units - Select “Metric” or “Imperial” as your preferred units of measure.

Driver info - Typically this is the name from the program file

Driver updated/version - Date loaded or updated and the version of the driver

Battery & Signal - Signal indicates the progress through the script. If driver fails to operate, signal number indicates progress

Driver status - Color and text of status bubbles give a quick visual reference of Communication, Operation, and Application

Communication - Com count indicates number of successful and unsuccessful data packets received
